Abstract
The utility model discloses a novel composite heat preservation pipe. The novel composite heat preservation pipe comprises an inner working steel pipe, wherein a silica aerogel heat preservation and thermal insulating layer is arranged on the outer wall of the inner working steel pipe, an aluminium foil reflecting layer is arranged outside the silica aerogel heat preservation and thermal insulating layer, an external protection steel pipe is arranged outside the aluminium foil reflecting layer, the space between the aluminium foil reflecting layer and the external protection steel pipe is filled with polyurethane heat preservation material, and an external anti-corrosion layer is arranged on the outer wall of the external protection steel pipe. According to the novel composite heat preservation pipe, the silica aerogel heat preservation and thermal insulating layer is arranged, the space between the aluminium foil reflecting layer and the external protection steel pipe is filled with the polyurethane heat preservation material, and therefore the heat preservation effect is good; the anti-corrosion layer is arranged on the outer wall of the external protection steel pipe, and therefore the anti-corrosion performance is good, the service life is long, and the novel composite heat preservation pipe can be applied to places with severe use environments such as the strong acid environment and the strong base environment.
